摘要：
The poly (L-lactide)/laponite composite films are prepared by the method of solution blending with polylactide (PLA) and laponite. The results show that when laponite content was lower than 0.2 %( mass w/w), laponite can be uniform dispersed in PLA and the composed material had good stability Fourier transform infrared spectroscopy (FTIR) study demonstrates that PLA was successfully incorporated with laponite by Si-O bond. The mechanical measurement reveals that the tensile strength of PLA/laponite composite film has been increased with compared to pure PLA. The water contact angle (WCA) tests indicate that the hydrophobicity of the laponite modified PLA films can be improved. The present study reveals that the laponite as a complexing agent can improve the mechanical properties and hydrophilicity of PLA.
